The application of confocal microscopy to the study of stone weathering
Technical and software bulletin 1993
Confocal scanning light microscopy is a valuable new method for examining the nature and progress of stone weathering at a level of resolution between optical microscopy and scanning electron microscopy. Not only is it non-destructive, but it can
Weathering pit characteristics and topography on Stone Mountain, Georgia
A detailed analysis of weathering-pit distribution on Georgia's Stone Mountain granite dome reveals a complex relationships between pit size and density, compared with slope aspect and angle. The AA. conclude that insolation weathering may be a more
important process in granite pit formation on Stone Mountain than commonly believed because afternoon temperature maxima accelerate weathering through increased chemical constituent dissolution and/or crystal constituent disintegration.

This study presents contradictory evidence. Till fabrics, clay minerals, indicator stones, morphology and elevation relationships all can be interpretated to indicate a Saginaw Lobe provenance for surficial drift on the moraine. The moraine
Set in rural New Mexico, the AA. describe a year-long integrated geography program that involves young students (ages 6-8) in a hands-on laboratory approach to exploring their immediate environment and providing a stepping stone
Remains of 200 wind-powered mills to grind sugar cane are found on the Caribbean island of Antigua. Many of these stone structures near the coast have now been renovated for use in tourism. - (DWG)
The island of Sjaelland on which Copenhagen is located is the stepping stone between scandinavia and Germany. The construction of bridges and tunnels across the narrow stretches of sea to the mainlands north and south would greatly facilitate
This paper reviews recent work on the effects of acid rain on building stones and explores its likely effects on karst. The impact on natural karst weathering depends on buffering capacity of the soil.
. The results at 320 cemeteries throughout North America and Hawaii demonstrate that air pollution (probably SO2) has been responsible for more deterioration of carbonate building stone and statuary than have other weathering processes.
Human activiy has affected the landscapes of karstic areas of the British Isles since the Mesolithic. Six main categories of human impact on limestone areas are considered in detail: ground-subsidence related; water related; quarrying; surface stone
